What: Staff from the Nuclear Regulatory Commission will meet with Southern California Edison rperesentatives to discuss its 2010 assessment of safety performance. The public will have the opportunity to ask questions.

San Clemente Green, an environmental group opposed to the continued operation of the San Onofre nuclear plant, is planning to protest a meeting today in which the Nuclear Regulatory Commission and Southern California Edison will field questions from the public.

Activists worry that instead of being a watchdog, the NRC too often rules in favor nuclear plant operators, said Gary Headrick, the organization's co-founder.

Protesters plan to gather about 5 p.m., an hour before the meeting is to start in San Juan Capistrano, he said.

At the meeting, NRC staff are to answer questions regarding oversight of the plant, where they have told operator Southern California Edison that there are still problems with worker culture.

The biggest problem, according to the NRC, is that workers are afraid they will be retaliated against if they bring up safety problems, something that's against the rules.

There has been progress, the NRC has said, but there is still work to do.

So far, the problems have not threatened the safety of plant workers or the public.
